DIVERGENT FLAP SEAL FOR GAS-TURBINE ENGINE EXHAUST NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a divergent flap seal preventing mechanical damage between adjacent divergent flaps of an exhaust nozzle, adaptable to complicated geometrical shape and useful to provide constant nozzle cross-sectional area. SOLUTION: A divergent flap seal 20 for a gas turbine engine exhaust nozzle having a longitudinal axis comprises a body 26, a spine member 28 and a flap position guide 31. The flap position guide 31 separates adjacent divergent flaps regardless of the angle of the flaps being skewed relative to the longitudinal axis of the nozzle, thereby more evenly distributing the flaps about the circumference of the nozzle.
